Application filed. August 25, 1914. Serial No. 858,538.

To all whom it may concern:

Be it known that I, JOHN R. MILLER, a citizen of the United States,residing at San Dimas, in the county of Los Angeles and State ofCalifornia, have invented a new and useful PressureRegulator, of whichthe following is a specification.

The present invention relates to improvements in pressure regulators,one object of the invention, being the provision of a simple andinexpensive as well as durable regulator of.this character, which isadapted to be connected between the water main and supply pipe, so thatany undue pressure within the supply pipe within the house from the mainmay be regulated as the faucet or the valve is turned off, so as toprevent any rupture 0r bursting of the pipes.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention. The invention is illustrated in the accompanying drawing,wherein the figure is a sectional view of the regulator, portions beingillustrated in elevation.

The numeral 1 designates the supply pipe which is led from the main (notshown) through the valve casing 52, and by the pipe & to the properoutlet. The coupling 5 is connected to the pipe 4 and has led therefrom,the branch pipe 6 which supplies the pressure fluid through the port 7into the' valve controlling chamber 8. The chamber 8 has mountedtherein, the plunger or piston 9, whose stem 10 is slidably mountedthrough the detachable cover 8 of the cylinder 8, and is connected tothe coupling 11, which also is connected to the lower end of the valvestem 12, which is connected to operate the cone valve 3. Thus as thepressure increases below the piston 9, the piston is elevated andthrough the yoke or coupling 11 it elevates and closes the valve 3.

In order to provide a means for regulating the action of the piston 9and consequently the action of the valve 3, due to the increased ordecreased pressure within the pipe 6, supplied through the pipe 4:, thebracket 13 is carried by the cylinder 8 and is connected by the link 14to one end of the regulating lever 15, said lever 15 being provided withthe recessed portion 16 within the coupling link 11 for engagement withthe cone end 17 of the piston rod 10, thus reducing the friction to aminimum at this point. In order to adjust the lever, the cylinder 8 hasat one end connected to it the coiled spring 19 while the opposite endof said spring is adj ustably connected by the adjusting screw 20 whichis connected to the free end of the lever 15 and is adjusted by means ofthe thumb screw 21. By this means, the action of the lever andconsequently the effect thereof upon the piston 9 may be adjusted to anexactness, so that the valve 3 is only operated when a predeterminedpressure is admitted to the lower end of the cylinder 8.

Any form of valve found most suitable, may be used.

What is claimed is:

In a device of the character described, a valve having a plunger, acylinder, a piston working in the cylinder and having a piston rodprojecting toward and in alinement with said plunger, a yoke connectingthe adjacent ends of said plunger and piston rod, the piston rod beingthreaded within one end of the yoke and having a cone point projectingwithin the yoke, the yoke having an opposite V-shaped bearing, and alever projecting through the yoke and resting against said bearing, saidlever having a recess opposite said bearing receiving said cone point.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
